Tony Mokbel may not have received a fair trial when he was sentenced to prison on drug trafficking charges because of his lawyer's double life as a police informer.
The head of an inquiry into the Lawyer X scandal, which saw a high-profile lawyer double as an informant, made the conclusions in a 2,000-page report which was released on Tuesday.
Mokbel had a professional relationship with lawyer Nicola Gobbo from early 2002, and he believed their conversations were subject to legal privilege.
'It was submitted that Ms Gobbo failed to disclose to Mr Mokbel her personal relationships with witnesses (both civilian witnesses and police officers),' the submission read.
'It was submitted that the circumstances in which Mr Mokbel was convicted of each charge gave rise to a substantial miscarriage of justice.'
Nicola Gobbo and drug lord Tony Mokbel were once close. She had acted as his lawyer but doubled as a police informant
Counsel assisting argued Victoria Police had an obligation to offer Mokbel a right to a fair trial, which included informing him or the court that his lawyer was a 'human source' in the investigation, Herald Sun reported.
During the inquiry, Commissioner Margaret McMurdo received recommendations that both Gobbo and Victoria Police should be the subjects of a criminal investigation.
Submissions by Chris Winneke QC, counsel assisting the royal commission into Ms Gobbo's informing, were released on Tuesday night.
'The submissions included contentions that I should find various named current and former Victoria Police officers and Ms Nicola Gobbo may have committed criminal offences,' Ms McMurdo said.
'I decided not to make findings in my final report, which will be publicly available, that any named individuals may have committed criminal offences.'
Tony Mokbel was stabbed almost to death inside jail. He hopes that he will soon be let free due to the meddling of his then lawyer Nicola Gobbo
Nicola Gobbo, who went into hiding, acted as a police informant while representing some of Victoria's hardened criminals
